Powering with the NT1 Power Supply
The ADTRAN NT1 Power Supply, part number 336048VUR2, provides up to 10 watts of power at -48 VDC. The
NT1 ACE requires 1.1 watts, leaving approximately 8.9
watts to power the TE(s). Before connecting any TE to be
6NT1 ACE
User Manual 61203019L1-1
NT1 ACE User Manual
powered from the NT1, verify that the total power requirement of the connected TE is less than 8.9 watts.
To connect the NT1 ACE to the NT1 Power Supply, perform
the following steps as illustrated in Figure 4.
1. Connect the Power Supply to the NT1 ACE at the
POWER jack located on the NT1 ACE.
2. Plug the Power Supply into the nearest wall outlet
supplying 110 VAC, 60 HZ.
3. On the NT1 ACE, verify that the POWER and ERROR
indicators are illuminated. After approximately 15
seconds, the READY indicator should flash at a 1 Hz
rate. Should any of the indicators fail to operate as
stated, see the section Troubleshooting on page 11.

Connecting the Terminal Equipment
After successfully powering up the NT1 ACE, the POWER
and ERROR indicators should be on and the READY indicator should be flashing. Make sure that terminal equipment
(TE) is properly terminated as instructed in Setting the
Option Switches on page 4. Plug the TE into one of the Local
Bus connectors at the rear of the unit. A second TE may be
plugged into the remaining Local Bus connector. If more
than two TEs need to be connected to the NT1 ACE, additional connections can be made in parallel to the S/T bus
using RJ-45 connectors.
.TEs commonly have additional jacks wired in parallel.
These may be used to connect more th an two TEs as provided for by the NT1 ACE. See the TE documentation for further information.
After the TE powers up, the ERROR indicator sh ould go out.
There may be some delay between plugging in the TE and
the ERROR indicator going out, depending on the specific
TE in use. If the ERROR indicator fails to go out, see the section Troubleshooting on page 11.
As the ERROR indicator extinguishes, the READY indicator
should illuminate. The TE will now be ready to place and
receive calls. There may be a slight delay between the
appearance of the READY indicator and the TE’s ability to
place and receive calls, depending on the specific TE in use.
If the READY indicator fails to illuminate or if you are
unable to place or receive calls, see the section Troubleshoot-
ing on page 11.
